The Island Koh Samui

The Island is a very good place to relax and forget your busy lives. The vibrant, bustling Chaweng is the heart of Koh Samui where both the young and old enjoy themselves until dawn. Towns like Fisherman’s Village provide a quiet retreat where shopping becomes a sightseeing haven as you explore the old style Samui architecture which has now been transformed into idyllic bars, restaurants and guesthouses.

The island is a shopping haven with night markets in various locations around the island on a near daily basis. On Monday’s The Wharf, located in Fisherman’s village becomes an all round entertainment venue with a market selling local Thai products and local bands playing Rock & Roll at the beer garden. Tuesday it is near the Tourism University. Wednesday it is near the Lake in Chaweng. Thursday it is in Maenam. Friday we go back to Fisherman’s village with the largest market of the week. Again you can be entertained by the local bands end enjoy many of the cocktails that are famous on Koh Samui. Saturday it is Chaweng. Sunday it is in Lamai. Also not to be missed is the local Temple Market which moves location every week so be sure to keep an eye out for the bright, neon lights for a real local shopping experience.
